Mussel-inspired dopamine-CuII coatings for sustained in situ generation of nitric oxide for prevention of stent thrombosis and restenosis.

Nitric oxide (NO) is a highly potent, yet short-lived bioactive molecule with a broad spectrum of physiological functions. Continuous and controllable in situ generation of NO from vascular stent surface can effectively prevent restenosis and thrombosis after its implantation.

In this study, inspired by the adhesion and protein cross-linking in the mussel byssus, through immersing the stents into an aqueous solution with dopamine (DA) and copper ions (CuII), we developed a one-step metal-catecholamine assembled strategy to prepare a durable in situ NO-generating biomimetic coating (DA-CuII). Due to the high NO catalytic efficacy and robust chelation of CuII into the DA-CuII network, the coated stents exhibited excellent hemocompatibility.

The coating also catalytically decomposed endogenous S-nitrosothiols (RSNOs) from fresh blood, and locally generated NO for over 30 days with a flux comparable to its physiological range (0.5-4 × 10-10 mol × cm-2 × min-1).

KT 5823 (PKG kinase inhibitor)

KT5823 is a potent, selective, and reversible inhibitor of Protein Kinase G (PKG). It is a derivative of K-252a. KT5823 has been shown to inhibit SNP-stimulated PKG activity in dispersed smooth muscle cells. It has also been observed to dose-dependen

Description: The substance KT 5823 is a pkg kinase inhibitor. It is synthetically produced and has a purity of ?98%. The pure substance is white solid which is soluble in DMSO (20 mg/ml), dimethyl formamide (20 mg/ml) and ethyl acetate (5 mg/ml).
